A nonstrict actor that performs an and operation on two inputs.

On each firing, produce an output token with a value with the value of the and if that output can be determined.

Constructor Detail

NonStrictAndGate

public NonStrictAndGate(CompositeEntity container,
                        java.lang.String name)
                 throws NameDuplicationException,
                        IllegalActionException

Construct an actor with the given container and name. Set the logic function to the default ("and"). Set the types of the ports to boolean.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

_allInputsKnown

protected boolean _allInputsKnown()
                           throws IllegalActionException

Return true if all inputs are known.

Overrides:

_allInputsKnown in class BinaryNonStrictLogicGate

Returns:

True if all inputs are known.

Throws:

IllegalActionException - If it fails.

_readInputs

protected BooleanToken _readInputs()
                            throws IllegalActionException

Read the inputs, and return the and function applied to all the are known and present.

Overrides:

_readInputs in class BinaryNonStrictLogicGate

Returns:

The logic function applied to all available inputs.

Throws:

IllegalActionException - If reading inputs fails.
